Someof the objects of the present inventionare to provide improved means for, playing a musical instrument; automatically to provide improved means for controlling several? organs comprising a' musical instrns ment; simult aneouly p to provide single means for. controlling the playing; of. the notes of a pipe onganiandfor. controlling the swell shutters thereot; to providean improved. form. of. control; mechanism for controlling the. swell shutters of; an. organ; andgto provide means for modifying the. act-ionq'ofl said control mechanism; :4 I d Other objects will-appear fromzthe following; description taken in connection. 1 with the accompanying drawing, in which there.

is shown so .mue'h of a. pipe organ, embody: ing the invention, asis neeessaryato an .understanding of the invention. y

Referring -.to the accompanying drawing one embodimentof this. invention comprises player mechanism 10, two SIIDllEIIYCOIltI'Ol} mechanisms 11- and .j12,;- each of which. controls: the swell. engines .13. and 14 of two organs. not; shown, and a pedalmechanisrn 15 for modifying the action-of thecontrol mechanisms .11 and .12.. The player. mechans ismiltlconsists of an air-tight bon 20 .pro-. vided in front with a removable plate: of, glass 21, a tracker bar 22 and;tWO:,me Ch3D-- ically operated rolls 23.. and 24. 'Mounted :upon these rolls is the. usual paper strip 25 provided with openingsrfor playin the.

, passing over thetraclrerbar 22. As air under In the operation of this form' of the in; vention shown in the accompanying figure,

the paper strip is unwound from the roll 23 and wound up upon the roll 24, thereby pressure passes in thru the pipe 31 from an outside source not shown, "theinterior'of 'the' box? 10 will be under pressure. The air will be prevented from passing into the holes of the tracker bar 22, as the paper strip '25 will'be pressed tightly against the face of the tracker bar As the paper strip 25 is moved across the tracker-bar 22, the openmgs 1n the paper pass in front of the corjresponding holes in the tracker bar 22. When an opening in the paper strip '25 passes in front of vany of the holes 28 or 29, a1r under pressure is adm tted to the correspond ng hole, thus sounding a corresponding note in the organ. The mecha;

nism up to this point-is of anywell-known mitted under pressure to the pipe 38,'and f thence to the bellows 60 which is thereby inflated the opening 62 being so small that standard'construction and design, and need" not be more fully descrihedherein.

When an open ng in the paper strip 25 PHSSGS'IH front of the hole 34, 911 ls'adonly a small amount of air is lost'thru thls means. This causes'the rod 55 to be 'moved to the left, as seen in the figure. T he tooth 56 engages the teeth of theratchet Wheel 49 which is thereby rotated through the distance of one toothand' the member which is rigidly secured thereto is there fore rotated through a like amount amount.

bellows 60 is deflated under the action of] Thelmember 45 is held in this' positionby means of the clicker 7 5 acting against the notched 6 wheel 50. The ratchet 51, being rigid with the ratchet 49, is alsorotatechbut asthe tooth 66 on the rod is out of the path of the ratchet teeth, it isnot engaged by them. After the opening inthe'paper 25 has passed beyond the hole 34, the supply of air is cut'oif fromthe pipe 38 and the I the return spring 61,' the air' escaping through the opening- 62. The' tooth '56 merely slides over the teeth of'th'eratchet 49 without turning the same, which "is held in position by -the clicker 75. The operation justdescribed causes the segment of conducting material 80 to be moved under the brush 83 thus closing the circuit through 7,

this brushconductor 91, terminal 94 and thence through the mechanism of the swell engine 13 to the'terminal 104, then through the return conductors 107 and 106 to the battery 90, the circuit being completed from this batter to the brush 82 by means of the Y conductor 88. The, swell engine 13 is thereby operated to open the swell shutters a small amount. s I I When another opening passes infront of the hole 34, a similar action to that just described takes place and the member 45' isrotated an additional amount sufficient to bring the contactsegment under brush 6 84. This closes the circuit through the terminal 95 of the swell engine' l'3, thus caus -mg the swell shutters of the corresponding organ to'be opened an additional amount. Thus, when a third opening passes in front of the hole 34, contact strip'80 is moved under the brush 84, thus closing the circuit through the terminal 96 which causes'the swell engine 13 toopen the swell shutters thefull amount. "If another opening should pass in front of the hole 34 the rod 55fwould be actuated, but the tooth 56' would not engage a tooth of the ratchet 49, as several teeth in this position have been cutaway so that the mechanism cannot be-moved farther m that direction.

When an opening in the paper 25 'passes in front of the hole 33, air under pressure is admittedto the pipe 37 and thence to the bellows 68 which is thereby inflated. This causes, the member 65 to .be moved to the, left and the tooth 66 to engage one of the teethfof the ratchet 51, thus causing the member 45'to be rotated'through a small angle. whichcorrespondsto the spacing of the teeth of the ratchet '51. This moves the contact'strip'80 so that it is no longer under the brush 85 and-thereby deenergizes the circuit through the terminal 96 which causes the/swell engine113 to" close the swell shutter a small amount. hen the second open- 'ing passes the hole33,t he operation is'repeated and the circu t through the terminal 951s deenerg zed thus causing the swell shutters' to'be closed an additional amount. A third opening passing in frontofthe hole 33 repeats this" action causing the swell shutters to be entirely closed thus returning the parts of the controlmechanism 11 to the position shown in the figure; If another opening shouldpass in front of the hole 33 the rod 65 would be actuated, but the-tooth 66 would not engage a tooth of-the ratchet 51, as severalteeth in this position have been cut away so that the mechanism cannot be movedfart-her in that direction It is. seen. from this description that the swell shutters controlledby the swell engine;

' 13 are opened successive amounts as open 7 mgs ln-the paper 25 pass in front ofthe hole 34 and are closed successive amounts'when swell shutters are indicated, but in actual practicethis number is. considerably increased.

The operation of the controlv mechanism 12is identicalto.that just described for the control mechanism 11, and is controlled by openings in the paper passing in front of the:holes:36 and 35, andrtherehy controlling the swell engine 14 in a manner previously described for the swell engine 13.

If it is desired to operate the swell shutters by means of a foot pedal 112, this is rotated, say, in a clockwise direction, as seen in the figure, which, by means of the link 111 and arm 110, rotate the shaft- 46 in a clockwise direction, which causes the two sectors 81 of the mechanisms 11 and 12 to be rotated through an equal amount thereby successfully bringing the contacts 83, 8d and 85 into engagement with the contact strip 80. By rotating the pedal 112 in an op posite direction, this action can be reversed, thus closing the swell shutters successive amounts.

The action of the pedal 112 can be superimposed upon the action of the two mechanisms 11 and 12 so as to modify their action as produced by the paper 25. For example, if the member of the mechanism 11 were in such a position as to energize the circuits controlled by brushes 83 and 8 1, the swell shutters controlled by the swell engine 13 would be open about two-thirds of the full amount. By rotating the'pedal 112 in a clockwise direction through a small amount, the swell shutters controlled by the swell engine 13 will be opened the full amount, whereas, if the pedal 112 is rotated in a counter-clockwise direction, it will cause the brushes 8% and 83 to move off the segment 80, thus closing the swell shutters which are controlled by the swell engine 13. This action is controlled from the panel 112 and modifies the action of the mechanismsll and 12.
